JOHN L. GOLES AND DAVID II. GOLES, OF BROOKLYN, ASSIGNORS TO THE EMPIRE STATE MANUFACTURING COMPANY, OF NEI/V YORK, N.l Y.

PARALLEL JAW-TOOL.

SPECIFICATION forming part of Letters Patent No. 424,274, dated March 25, 1890.

Application tiled June 6, 1889. Serial No. 313,352. (No model.)

To all whom it may concern:

Be it known that we, JOHN L. GOLES Aand DAVID H. GOLES, both citizens of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Parallel Jaw-Tools, of which the following is a speci fication.

This invention relates to a parallel jawtool which shall be capable of easy operation and adjustment; and the invention consists in the details of construction set forth in the following specification and claims, and illustrated in the accompanying drawings, in which- Figure l is a side elevation of a parallel jaw-tool. Fig. 2 is a plan view of Fig. l. Fig. 4 isa detail sectional elevation showing the inner side of a bracket. Fig. 5 is a detail view of a fulcrum. Fig. 6 is a section along line x oc, Fig. l. Fig. 7 shows a tool secured to a jaw.

G G, fixed to the jaw A by riveting, welding,

or by being formed integral with the jaw. The bracket has a way or guides D D for the fulcrum E of the jaw F. The jaw F, as seen in Fig. l, is made to pass more than halfway about the fulcrum E, so that said jaw is secured to the fulcrum and moves with the fulcruin as the fulcrum is adjusted back and forth along the way D. A nutI'I, engaging the screw I, serves to adjust the fulcruins along the way D. The nut H is held in place by a support K, which is secured to the bracket G G in any suitable way, as by riveting, doweling, soldering, or screwing. The movable jaw F has a handle G. The fulcrum F. can be adjusted so that the jaw F will be at such a distance from the jaw A that only a slight movement of the jaw F is required to enable a nut or other object to be grasped between the jaws A F, so that the jaws A F can be left practically parallel to one another during the operation of the tool. The handle G is made to move in a slot L in the handle B, whereby the handle G is prevented from moving laterally.

The jaws A F can be used for various purposes, such as to grasp nuts or bolts or to support various tools-*such as belt-punches, shears, snips, various-shaped pincherjaws, pliers, and other tools-which may be readily secured to or taken from the jaws A F. The parallelism of the jaws and the adjustability of the jaws toward and from one another will insure accurate relative position of the tool parts-wis, for example, of the male and female parts of a punch.

In Fig. 7 a punch is shown secured to a jaw. By beveling the jaw and making the engaging portion of the tool in dovetail shape the tool can -be readily slipped onto the jaw.

lVhat we claim as new, and desire to secure by Letters Patent, is

l. A parallel jaw-tool consist-ing of a rigid jaw A, having a handle B and a slotted bracket provided with guides D, a support K on the `end of the bracket, a rotating nut H between the support and the bracket, an adjustable screw I, passing through the support and nut and formed at its inner end with a fulcrum E, and a jaw F, journaled and swinging on the fulcrum on the inner end of the screw and having a handle G, disconnected from the handle of the rigid jaw, substantially as described.

2. A parallel jaw-tool adapted for the Inale and female parts of a punch, consisting of a rigid jaT A, having a handle B, provided with a slot L, and a slotted bracket provided with guides D, a support K on the end of the bracket, a rotating nut II between the sup port and the bracket, a screw I, passing through the support and nut and formed at its inner end with a fulcrum E, and a jaw F, journaled and swinging on the fulcrum on the inner end of the screw, and having a handle passing through and disconnected from the slotted part of the handle on the rigid jaw, substantially as described.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
